Factors Affecting Risk of Musculoskeletal Disorders (MSDs) Complaints in Spring Production Workers

Abstract

Introduction : Musculoskeletal Disorders (MSDs) are one of the occupational diseases with complaints that
felt in the skeletal muscle. Musculoskeletal complaints can occur in any sector of work. one of the sector is
in informal sector workers. The aim of this research was to analyze the relation between individual factors
with occupational factors on musculoskeletal complaints in spring production workers.
Methods : This research was an observational research with cross sectional approach. The sample in this
research was 23 respondents in the production unit. Sampling in this research was conducted by total
population. Data of respondent characteristics musculoskeletal complaints were obtained through interviews
conducted to respondents by filling out standardized questionnaires. Work posture data were analyzed using
Rapid Entire Body Assessment (REBA) and musculoskeletal complaints data were analyzed using the
Nordic Body Map (NBM) method. Statistical tests were analyzed using the Contingency Coefficient test.
Results : The results of the research to 23 respondents showed that the majority of respondents as many
as 15 respondents (65.21%) had MSDs complaints in the high pain severity category. Risk factors related
to Musculoskeletal Disorders complaints were age. smoking habit. sex. nutritional status. works duration.
work posture and physical workload. The data obtained were analyzed using the Contingency Coefficient
test.
Conclusion : Factors causing Musculoskeletal Disorders that had the strongest relationship were odd or
non-ergonomic work posture of workers (r = 0.632) with positive relation direction. meaning that the higher
the risk of work posture. the higher the risk for experiencing MSDs complaints.
